23621

Analysis

NAICS 23621 is the 2022 NAICS industry for industrial building construction, part of 2362 (Nonresidential Building Construction).

It has only one more detailed code, 236210, which covers exactly the same activities; the definition, index entries and statistics are on that page.

County Business Patterns counts 3,380 US establishments in this code in 2023, employing 75,224 people at an average annual payroll of $92,768 per employee (80th percentile of national industries). 49% of the establishments have fewer than five employees, which is close to the national mix.

By establishments it ranks 2nd of the 2 codes at this level within Nonresidential Building Construction, with 8% of them.

Between 2018 and 2023 the number of establishments grew 4% and employment rose 6%. The 2018 count used NAICS 2017, so part of a large move can come from codes being redefined rather than from businesses opening or closing.
